Have you ever owned an iPhone? Because as others have said it sounds like Apple's iMessage system thinks that you have an iPhone and so the iPhones are trying to send you iMessages (which only iDevices can receive). It's odd for this to suddenly start, because usually the way this happens is that someone switches to Android but doesn't remember to sign out of iMessage first, with the result that iPhones think they are still iMessage users. Apple eventually (when threatened with class action lawsuits, not before) provided a way of signing out over the web without an iPhone, so if you were previously an iPhone user maybe you should look this up and give it a try, because it could be that something has gone wrong there and they have re-activates iMessage on your account? As I say, I've not heard of that before, but logically it's possible and could produce this result.
(This whole mess is indeed corporations doing what corporations do, i.e. being self-serving and to hell with their customers. Apple did discuss internally making iMessage cross-platform, but decided to keep it Apple-only to help lock in their users. They also took no action on the problem I described above for about 2 years before legal threats forced them to act: it suited them, because many switchers would assume that the problem was that Android was broken and switch back. Then a few years ago Google tried pushing networks to adopt the RCS standard for advanced messaging (which they did not invent but are currently the only users of) in a transparent effort to undermine iMessage by having a universal, built-in first party advanced message system. Apple of course refused to allow it on iPhones, so few networks adopted it, and so we now have a situation where Google's Messages app and Samsung's Messages app support iMessage-like features through an RCS system hosted by Google, which effectively mirrors iMessage on iOS: very similar features, hosted by the OS owner, only available on one platform.
In Europe at least most people deal with this by just using a third party app that works across platforms. So the main beneficiary of this mess has been Facebook, because they own WhatsApp...).
